Cote D’Ivoire: Rialto Completes Gazelle Well With “Good Gas Rate”

Rialto, the AIM listed minnow, has Rtested gas flow rate of 19.5 million standard cubic feet per day (19.5MMsf/d) of gas aswell as 133 barrels of condensate per day (133BCPD) in its first operated well in Block Cl-202, offshore Cote
Rialto has now completed the Gazelle-P3 ST2well testing programmeand the well will now be suspended for future use.
The company reported that 40 API Oil was recovered at an unstabilised rate of 760 BOPD prior to well ‘channelling’ gas. “The flow rates confirm productivity of UC-1 reservoir sands”, a press release said.
“The maximum gas flow rate was constrained due to downhole equipment limitations. The estimated deliverability of the reservoir with standard 4.5″ production tubing rather than the 3.5″ test string is 33MMscf/d”, Rialto said. “The main DST focused on the Upper Cenomanian (UC-1C) gas reservoir (over the interval 2632.9-2666.6 mMDRT), successfully achieving an average flowrate during a ten hour period of 17.5 mmscfd gas through a 44/64” choke,
with a flowing wellhead pressure of 1470 psia”.
Prior to undertaking the oil test, cement bond logs indicated that the zones may not be hydraulically isolated in the well bore. As a result, the UC-1A oil reservoir (perforated over the interval 2678.0- 2713.2 mMDRT) achieved an unstabillised flow rate of 760 BOPD before gas, originating from the overlying gas reservoir via behind-casing
channelling, prevented further oil flow from this interval.
